Transformers Sense Up To 40A

Coilcraft's CST2020 Series current sense transformers sense current up to 40A over a frequency range of 400 Hz to 1 MHz and offer 4 kVrms isolation voltage between the sense and output windings. They provide reinforced insulation per UL 60950-1 and output feedback for load current measurement and control in switching power supplies and overload/short-circuit protection. They are qualified to AEC-Q200 Grade 1 (-40°C to +125°C) standards, making them ideal for automotive applications like current measurement in traction motor and battery management systems. They are also well suited for use in 48V vehicle systems. Other applications include aerospace power management systems, three-phase solar inverters, industrial motor controls and other applications requiring high isolation between the sense and output windings.

The CST2020 Series is available with four turns ratios ranging from 1:70 to 1:300, and offers a sense resistance down to 0.00084Ω.
